This application is a continuation of U.S. application Ser. No.16/283,573, filed on Feb. 22, 2019, for MEDICAL DEVICE, which is acontinuation of PCT Application No. PCT/CN2017/098692, filed Aug. 23,2017, titled MEDICAL DEVICE, each of which is incorporated herein byreference.

TECHNICAL FIELD

The present disclosure relates to medical devices, and in particular toa medical device that is able to quickly switch configurations fordifferent scenarios.

BACKGROUND

In conventional medical devices, it is sometimes beneficial torespectively connect multiple components to a housing, and the housingusually uses a split-type plastic housing. The plastic housing isimpacted by the capability to make a mold and the processes ofproduction and installation. The housing is thus generally divided intoa front housing component, a rear housing component and other componentsassembled together.

Because there are many components, the whole housing is also dividedinto a large number of blocks, resulting in an unaesthetic appearance ofthe whole machine, such that beautifying lines or mating lines need tobe added at the mated positions for improving the appearance. It isbeneficial to design a special structure for connecting severalcomponents when they are assembled simultaneously.

General structural connections usually use screws, snap-fit fasteners,etc., and the connections are easily damaged by force. In particular,when replacing internal components and during maintenance, theconnection structure needs to be disassembled and assembled frequently,and the connections are easily damaged by force to cause failure or isdamaged by falling, which affects the normal use of the medical device.

Moreover, a stressed plastic part may be cracked after wiping with anexisting medical cleaning and disinfecting agent. To solve the crackingproblem, plastic materials with better chemical resistance are generallyused in the existing market, resulting in high production costs.

Moreover, a conventional medical device generally uses a functionalmodule of a standard configuration or an optional configuration ofvarious parameters (ECG module\SPO2, module\TEMP, module\CO2 module,etc.), and the medical device is structurally designed with themaximized configuration, resulting in a relatively large volume of themedical device, which makes it inconvenient to transfer in a hospital,let alone on a battlefield or in a field rescue.

What is needed is a medical device that facilitates easy and

Referring to FIG. 6 , the main bracket 31 of this embodiment is furtherfixedly provided with a thermal isolation compartment 309 foraccommodating the battery or the functional module 32. The thermalisolation compartment 309 may be a metal chamber, e.g., the side wall ofthe thermal isolation compartment 309 may be made of metal. A thermalisolation member 311 is arranged in the housing 1, and the thermalisolation member 311 may be connected to the main bracket 31 to form athermal isolation and separation space. One end of the thermal isolationmember 311 is connected to the side wall of the thermal isolationcompartment 309, and the other end of the thermal isolation member 311is connected with a heat dissipating surface shell 15 to improve theheat dissipation performance in the thermal isolation compartment 309,so that the battery or the functional module 32 in the thermal isolationcompartment 309 can operate within a suitable temperature range.

The thermal isolation member 311 may be made of a material having a highthermal conductivity, e.g., a metal material such as copper or aluminum,and the thermal isolation member 311 may also be a heat pipe.

In this way, the internal heat dissipationproblem can be solved by reducing the battery temperature. Compared withthe solutions using heat dissipation by air convection, heat dissipationby metal heat sink, heat dissipation by silica gel and the like inconventional approaches, the medical device provided by the embodimentisolates regions having different heat requirements and then dissipatesheat for specific regions, so that the heat dissipation effect isimproved by the material change of the housing 1 without adding aspecific heat dissipation module. As a result, the heat dissipation ismore targeted, the product cost is low, the heat dissipation can beperformed through the structural member of the housing 1, and theappearance effect is better.

Referring to FIG. 6 , in this embodiment, a thermal isolation materiallayer 312 may be arranged on the side wall and the end of the thermalisolation compartment 309. The thermal isolation material layer 312 maybe a plastic member thermal isolation layer, the battery and otherthermal elements in the thermal isolation compartment 309 are thermallyisolated by the thermal isolation compartment 309 and the thermalisolation material layer 312, so that the battery compartment alonebecomes an air-conditioned room, which is not affected by the heatingdevice inside the machine, thereby further improving the thermalisolation effect.

Referring to FIG. 12 , in other embodiments, at least one exposed window109 is arranged on a lateral side of the housing 1, and a part of thethermal isolation compartment 309 extends to the exposed window 109.

This can directly dissipate heat by radiation to theoutside. The heat dissipation path is short, and the battery or othercomponents in the thermal isolation compartment 309 can achieve betterheat dissipation performance, so that the battery (main battery) orother components in the thermal isolation compartment 309 can workwithin a suitable temperature range. This further improves the stabilityand reliability of the device.

Especially in a miniaturized device which is small and compact and hashigh heat dissipation requirements, such a structural design can makethe device meet the requirements of heat dissipation in the miniaturizedapplication. The thermal isolation compartment 309 can be made of ametal or a high thermal conductivity plastic or composite material forbetter heat dissipation.

Furthermore, after thecombination of one or more of the above components is completed, asealed inner cavity can be formed in the housing 1. For example, in oneembodiment, the housing 1 is combined with the combined modularstructure 3, the screen assembly 2 and the compartment cover 350 to forma sealed inner cavity in the housing 1. The exposed part 342 is providedwith a venting groove 3421, and the venting groove 3421 communicateswith the outside air and the sealed inner cavity.

One side of the venting groove 3421 may be provided with a bloodpressure measurement air inlet. The exposed part 342 may be attachedwith an exposed plate 343. The exposed plate 343 can be capped over theventing groove 3421, and only a part of the venting groove 3421 (e.g.,the front end 3422) can be exposed. The exposed plate 343 may be a metalmember and may pass through the exposed plate 343 by means of a screw,and the exposed part 342 is locked to the main bracket 31 or the housing1.

In one specific application, theventing groove 3421 may be of a curved shape, a polygonal shape or thelike, e.g., a regular curved shape such as an S-shape or a wavy shape oran irregular curved shape. The front end 3422 of the venting groove 3421is exposed, e.g., the front end of the venting groove 3421 communicatesdirectly with the outside air, so that the venting groove 3421 can alsoserve as a heat dissipating passage while venting. In the illustratedstructure, the front end 3422 of the venting groove 3421 is located atthe edge of the exposed part 342.

It can be understood that the front end 3422 of the venting groove 3421may also be located at other suitable positions, e.g., at the middle ofthe exposed part 342 and the like.

In order to increase the grade of waterproof of the whole device to theIP44 level, in addition to the aforementioned structures, the structuraldesign can also be considered. For example, in one embodiment, theexposed part 342 and the exposed window 109 are located on one lateralside of the housing 1, and the lateral side is parallel and adjacent tothe end face where the first opening is located. When the screenassembly 2 is on the front side, the exposed part 342 and the exposedwindow 109 are located on the bottom side of the housing 1.

In addition, the housing 1, as a whole, is a sealed structure inaddition to the first opening 101, the second opening 102, the exposedwindow 109 and the opening mated with the compartment cover 305. Inorder to better realize the sealed structure, the housing 1 adopts anintegrally formed structure. The second opening is located at the sidesurface of the housing 1, and the connection (such as the first opening101) between the combined modular structure 3 and the housing 1 issubjected to a waterproof sealing process by a sealing rubber ring orthe like, and the connection (such as the second opening 102) betweenthe screen assembly 2 and the housing 1 is also subjected to awaterproof sealing process by a sealing rubber ring or the like, so thatthe whole device can achieve the waterproof effect of IP44 in additionto the beneficial ventilation and heat dissipation effects.

In oneembodiment, the housing 1 has only three lateral sides with an opening,while the other three sides have no opening. In particular, the threesides with an opening are perpendicular and adjacent to each other.
